Rc8, Rxc8, Qxc8

I don't think the third and fourth positions are mates in two.

First one, 1.Qc4+ Kh8 2. Qc8#
Second one, 1.Rg8+ Kxg8 2.Rg1#
Third one isn't in two moves
Fourth one isn't in two moves
Fifth one 1.Bb5+ 2. c6 2.Re7#
Sixth one is actually a mate in three: 1.Rd1+ Rxd1 2.Rxd1+ Kh2 3. Qh4#

The sixth one is white to move. So, 1. Rc8 Rxc8 2. Qxc8#

1.Qc4+ Kh8 2.Qc8#

In the 2nd puzzle:

1.Rg8++! Kxg8 2.Rg1#

5th puzzle:

1.Bb5+! c6 2.Re7#

What is the answer in the 4th puzzle?
